Live A Sanctified Life
Paul spoke this in love, not ridicule. A warm reminder to us of what sanctification is. A warning so we will not be lulled asleep by our flesh, apple if you will.
The enemy knows what will make us guilty of Father's rath, hoping we would be so overcome with guilt and shame so to close our eyes to the cross, forgetting our redemer, Jesus Christ of Nazareth . The one who sanctified the flesh through His death and resurrection.
"For this is the will of God, your sanctification; that is, that you abstain from sexual immorality; that each of you know how to possess his own vessel in sanctification and honor, not in lustful passion, like the Gentiles who do not know God; and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you. For God has not called us for the purpose of impurity, but in sanctification."
1 Thessalonians 4:3-7 NASB
